Proinflammatory Cytokines Suppress Nonsense-Mediated RNA Decay to Impair Regulated Transcript Isoform Processing in Pancreatic β-Cells

S. Ghiasi, P. Marchetti, L. Piemonti, J. Nielsen, B. Porse, T. Mandrup-Poulsen, G. A. Rutter

This study shows proinflammatory cytokines suppress NMD activity in β-cells by downregulating UPF3B, leading to increased alternative splicing and ECM-related gene expression, which contributes to β-cell dysfunction.

LRH-1/NR5A2 Activation Rewires Immunometabolism Blunting Inflammatory Immune Cell Progression in Individuals with Type 1 Diabetes and Enhances Human Islet Function in Mice

N. Cobo-vuilleumier, S. Rodriguez-Fernandez, L. Lopez-Noriega, P. I. Lorenzo, J. M. Franco, c. C. Lachaud, E. Martin-Vazquez, R. Araujo Legido, A. Dorronsoro, R. Lopez-Fernandez-Sobrino, b. Fernandez-santos, D. Salas-Lloret, N. van Overbeek, M. Ramos-Rodriguez, C. Mateo-Rodriguez, , B. R. Gauthier

This study shows that activating LRH-1/NR5A2 reduces inflammation in T1D by altering immune cell metabolism and improves human islet function in mice.

High-resolution glucose tracing and in situ imaging reveals regulated lactate production in human pancreatic β cells

F. Cuozzo, K. Viloria, A. H. Shilleh, D. Nasteska, C. Frazer-Morris, Z. Jiao, A. Boufersaoui, B. Marzullo, H. R. Smith, C. Bonner, J. Kerr-Conte, F. Pattou, R. Nano, L. Piemonti, P. R. Johnson, , D. J. Hodson

The paper uses metabolic tracing and imaging to show that human pancreatic β cells produce lactate, regulated by LDHB expression, which affects Ca2+ spiking without altering ATP/ADP levels.

Roles for the long non-coding RNA Pax6os1/PAX6-AS1 in pancreatic beta cell identity and function.

L. Lopez-Noriega, R. M. Callingham, A. Martinez-sanchez, S. Nawaz, G. Pizza, N. Haberman, N. Cvetesic, M.-S. Nguyen-Tu, B. Lenhard, P. Marchetti, L. Piemonti, E. J. P. de Koning, A. M. J. Shapiro, P. R. Johnson, I. Leclerc, , G. A. Rutter

This study investigates the role of Pax6os1/PAX6-AS1 in beta cell identity and function, finding that its upregulation in diabetes contributes to impaired functionality and that targeting it may improve glucose homeostasis.
